Kind of a novice and have never used anything but veg tan for my projects (purses, sheathes, holsters, etc.) and am not familiar with chrome tanned at all. I found a nice pattern for a messenger bag that I want to make and the main body is spec'd as ' 5 oz chrome tanned leather'. I think I'd rather use veg tanned for the whole thing but, I believe, chrome tan is not as stiff as veg. Could I use thinnner veg tan to get the same effect? The 'wrap-around' sides/body and trim/straps is natural veg colored and the chrome tan body is a darker brown. I'd like to use a thinner veg tan and dye it darker - does that sound reasonable? Hope I asked this so it's understandable.
